How it works
How YieldLens UK works
Commercial lease pressure-testing before you sign. YieldLens UK turns rent, revenue, costs, opening cash, and downside assumptions into an indicative viability view before a lease becomes expensive to unwind.
YieldLens UK provides indicative decision-support only. It is not a valuation, financial advice, mortgage advice, legal advice, tax advice, or a substitute for professional due diligence.
In one line
It turns lease assumptions into a structured early warning view.
The point is not to promise certainty. The point is to make the rent, trading, opening cash, and lease questions easy to review before you commit.
What it asks
- Can the business carry the rent?
- Does the opening buffer look thin?
- What happens if trade starts weak?
Why this exists
A lease can look fine until the real costs are added.
Commercial tenants often focus on whether a site looks good. The harder question is whether the site can carry the rent after fit-out, deposits, staff, supplier costs, and a weaker-than-planned start.
What the free commercial check does
The free result is the fast viability snapshot.
It gives the headline numbers you need to decide whether a site deserves more time.
Rent burden
Shows whether rent still leaves room for staff, stock, service charge, and slower early trade.
Break-even customers
Turns the rent and cost base into a daily customer target so optimistic trade assumptions are easier to challenge.
Opening cash
Shows whether fit-out, deposit, legal fees, stock, and launch costs leave enough buffer.
Downside trading
Checks what happens if early trade lands below the best case.
Six-month survival
Shows whether the site can absorb a weak start or needs better terms before signing.
Risk flags
Surfaces the pressure points that deserve another look before the lease gets expensive to unwind.
How to read the result
The score is a screening signal, not a final answer.
A good score means the entered assumptions look more workable. A caution or fragile result means the assumptions, rent terms, evidence, and cash buffer need more checking. The result is only as useful as the numbers entered.
What the £49 Standard Commercial Viability File adds
The paid file turns the snapshot into a decision memo.
It keeps the same numbers but organises them into a printable report the user can use for negotiation and due diligence before signing.
Proof in practice
The metrics work together, not in isolation.
Each check answers a different part of the lease question, and together they show where the pressure sits.
Rent burden
Checks whether rent still leaves room for staff, stock, service charge, and quieter early trade.
Break-even customers
Turns the rent and cost base into a daily customer target so optimistic footfall assumptions are easier to challenge.
Opening cash
Shows whether fit-out, deposit, legal fees, launch stock, and setup costs leave enough breathing room.
Downside survival
Checks whether a weaker start still gives the operator time to adjust.
Evidence checklist
Reduces assumption risk by showing what should be verified before signing.
Methodology
How YieldLens checks commercial lease viability
It is built for early screening, not for market valuation or full professional review.
Step 1
Enter the lease and trading assumptions
Add rent, revenue, costs, opening cash, and downside assumptions from the site you are checking.
Step 2
YieldLens organises the assumptions into a viability snapshot
The free check pulls the numbers, known lease costs, and evidence gaps into one view so the pressure points are easier to compare.
Step 3
Review rent burden, opening cash, break-even pressure, and downside risk
The snapshot shows whether the lease looks fragile once the opening and downside cases are included.
Step 4
Use the £49 file if you need a printable decision memo
The Standard Commercial Viability File turns the same result into a printable memo with lease questions to raise before signing.
Before signing guides
Before the assumptions harden, check the lease questions that sit behind the numbers.
Commercial lease checklist before signing
Use the hub that groups the main lease checks.
Commercial heads of terms before signing
Check the early deal points before the lease gets expensive.
Commercial lease costs before signing
Check the full cost stack before you commit to the lease.
Commercial break clause before signing
Check the exit route if trading weakens after opening.
What users should verify before signing
The checks that matter before the lease becomes hard to unwind.
These are the items that should be checked after the commercial result but before commitment.
Illustrative example
A fictional cafe example shows how the questions sharpen.
The example is fictional and redacted so the reasoning path can be seen without exposing a real tenant or property.
Fictional case
A fictional cafe operator is comparing a unit with strong footfall but a rent level that looks heavy once the full cost stack is included.
YieldLens points to a high rent burden, a break-even target that needs checking against real footfall, and an opening cash buffer that looks thin after launch costs.
That pushes the operator to ask about rent-free time, landlord contribution, fit-out scope, service charge, and evidence for demand before signing.
Before and after pressure-test
Before: high rent burden
Rent absorbs too much of the monthly revenue, leaving less room for staff, stock, service charge, and quieter weeks.
Before: demanding break-even target
The daily customer target only becomes useful when it is compared with seating, opening hours, and realistic trade patterns.
After: better opening terms
A rent-free period, lower deposit, or landlord contribution can improve the opening buffer and make launch pressure easier to carry.
After: stronger negotiation position
A break clause and clearer evidence for demand turn the result into a better conversation before signing.
YieldLens would push the user to challenge the rent, confirm footfall, verify fit-out costs, and review lease clauses before committing. The paid file then organises the same result into the memo used for negotiation and due diligence.
What YieldLens does not do
The limits are deliberate.
The tool is there to help with early screening and decision support, not to replace the people and evidence that close the deal.
